NEET Chemistry QUESTION #7402
Question 1
Which of the following oxides is NOT expected to react with sodium hydroxide?
  • BeO
  • \(\text{B}_2\text{O}_3\)
  • CaO✔️
  • \(\text{SiO}_2\)
Correct Answer Explanation
Reaction with NaOH (basic): Only acidic or amphoteric oxides react with NaOH.
  • BeO: amphoteric → reacts with NaOH
  • B₂O₃: acidic → reacts with NaOH
  • CaO: basic → does NOT react with NaOH (two bases don't react)
  • SiO₂: acidic → reacts with NaOH → Na₂SiO₃
